Distinct meeting descriptions for templates

Aaaargh, I did it again!  It's totally unclear that when you update the default meeting description for a template that you are updating it for ALL templates. And as far as I can see, there is no Undo/Restore. 

Is there any way to have the meeting descriptions be on a per-template basis? I see only minimal advantage (and major disadvantage) is having a single global meeting description across all templates.

Only change the meeting description once it becomes a dated agenda.

Recover by copying from an existing dated agenda.  Only dated agendas created after the change in Agenda Settings will be affected.
